RUNCCI-YUN 3pcs Mini Water Pump DC 3V 5V Micro Submersible Motor Pump, Mini Brushless Water Pump+ 3M Clear Vinyl Tubing Flexible PVC Tubing for Fish Tank Fountain Aquarium Garden

Worked well, fit for purpose

They are great, powerful and quiet. However they are not suitable for anyhing food related so do remember that, also when storing, makes sure they are dry otherwise they will rust like mine but that was after a year.

After buying these a long time ago I have finally used them. They all work and seem to be of a decent quility No idea how long they will last though.

Unfortunately one out of three motors was faulty. Had continuity, just not rotating - disappointing.

came on 21st July all three tested and working only needed and used one. connected to 3 rechargeable AAA in series and a switch chucked it into my 600mm x 450mm tray of water and watercress connected to short piece hose (300mm) cut off the long hose supplied that what was supplied. I only run for 15mins 4-5 times a day and change the batteries after 3days (or sooner if I forget to switch off) Watercress has thrived (but that could be the nutrients added to the water:)) today is 15th September and the pump is still going strong. I also have a couple of solar pumps in different trays and the results are roughly the same. For the price what is not to like.

These pumps are impressive. We used them for my daughter’s school project, and they performed well. I was genuinely surprised by the pressure they produced. We powered them with 2 × AA batteries (3 V), as using 3 × AA (4.5 V) created too much pressure. Based on the specs, they should provide several hours of runtime. One reason I chose this model is because it came with tubing included. However, the supplied pipe is a slightly awkward, non-standard size. I ended up buying different tubing so I could use standard barb connectors instead. Unfortunately, one of the pumps only functioned for a few seconds, which makes me slightly sceptical about the product’s quality control and long-term reliability.

These are very quiet & efficient. For the money I reckon they’re excellent value. I’ve used mine to make my own bilge pump in a 1 metre model boat. Recommended.

Bought this for my sons experimental electronics project , did the job. Would have preferred longer wires on the pumps but we found a workaround.

Conforme à la description. Fonctionnent tous parfaitement.

Grundsätzlich tun die Pumpen das was sie sollen, Preis-Leistung ist hier sehr gut, es ist auch ein relativ hoher Durchsatz mit ordentlich Druck für die Größe (aus der Öffnung kommt der Strahl bestimmt 20 cm hoch). Eine Pumpe war kaputt, also hab ich den Verkäufer angeschrieben, dieser hat sehr schnell geantwortet und mir angeboten 3€ zu erstatten, das hatte ich dann auf 4€ hochverhandelt und mir wurden dann zügig 4€ plus Mehrwertsteuer erstattet. Support anschreiben lohnt sich fast immer :) Danke für's lesen!

Thank you

As bombas são bastante compactas mas têm um desempenho muito bom para o tamanho. Funcionam de forma simples, fazem pouco ruído e conseguem movimentar água com um caudal perfeitamente adequado para pequenos projetos. O facto de virem três unidades também é uma grande vantagem, porque dá para usar em diferentes montagens ou ficar com suplentes. Muito práticas para projetos DIY, pequenas fontes, refrigeração ou outras aplicações semelhantes.

Ottimo e funzionante
